IMPROVEMENT IN WINDMSILLS.

Specification forming part of Letters Patent No. 197,796, dated December4, 1877; application filed October 27, 1877.

To all whom it may concern:

Be it known that I, J OHN J REED, of Lyons, in the county of Clinton andState of Iowa, have invented a new and useful Improvement in Windmills,of which thefollowing is a specification:

Figure 1 is a side View of my improved windmill, partly in section, toshow the construction. Fig. 2 is a top view of the same, parts beingbroken away. Fig. 3 is a top view of the vane or tail.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved windmill, whichshall. be so constructed that the action of the wind, as it increases inforce, will turn the wheel more and more out of the wind, and finallystop it, that it may be readily stopped by hand and fastened out of thewind, and which shall be simple in construction, and not liable to getout of order.

The invention consists in a windmill in which the vane is connected withthe rotating barrel that carries the wind-wheel by a plate or framehinged to said barrel, and to which the said vane is hinged; in thecombination of the lever, the connectingrod, and the arm with the hingedvane and with the rotating barrel that carries the wind-wheel; and inthe combination of the inclined boards or wings with the sides of thehinged vane, substantially asherein shown and described.

A represents the tower or frame that supports the mill, and to the topof which is attached a hollow pivot, B. Upon the pivot B revolves asleeve or band, 0, upon the forward side of the upper end of which isformed ahollow arm, D. E is the wind-wheel,which is constructed in theusual way, and the shaft F of which passes through the vhollow arm D,and has a crank or crank-wheel, G, attached to its inner end. To the pinof the crank or crank-wheel G is pivoted the upper end of the rod H,which passes down through the cavity of the barrel 0 and pivot B, and isconnected at its lower end with the pump or other machinery to bedriven. The rod H should have a swivel formed in it, to prevent it frombeing twisted by the turning of the barrel 0 upon the pivot B. Upon theupper and lower parts of the rear side of the barrel 0 are formed lugsI, to which are pivoted the upper and lower corners of the triangular orthree-armed plate or frame J by a rod, K. The upper edge of the plate Jis horizontal, and to it, near its forward end, is hinged the end of thecentral bar of the vane or tail L, which bar, when the vane L is in ahorizontal position, rests upon a rubber block, M, attached to the upperedge of the rear or third corner or arm of the plate J, to prevent noiseas the said vane drops into a horizontal position. The vane L is kept inthe same vertical plane with the plate J by the bars N 0 attached to theopposite sides of the forward part of the central bar of thesaid vane'L, and which project down upon the opposite sides of the said plate J.The bar 0 is strengthened by an inclined brace, P, the lower end ofwhich is attached to the said bar 0, and its upper end is attached tothe central bar of the vane L in the rear of the upper end of the saidbar 0. The bar 0 is extended downward, and to its lower end is pivotedthe end of a rod, Q, the other end of which is pivoted to the end of anarm, R, formed upon or rigidly attached to the lower part of the barrel0, midway between the arm Dand lugs I. To the opposite sides of the rearlower part of the vane L are attached boards or plates S, which inclinedownward, and to which are attached extension-boards, so that the saidboards or wings can belengthened or shortened, to make them more or lesssensitive to the wind.

With this construction the wind blows against the under sides of theinclined boards or wings S, and tends to raise the rear end of the vane.

As the vane rises, the lever O and rod Q draw upon the arm R, and turnthe barrel so as to tend to bring the wheel E parallel with the vane L,and thus take the said wheel E more or less out of the wind, accordingto its force.

To the forward part of the central bar of the vane L is attached a'baror rod, T, which inclinesupward, and to which is adjustably attached aweight, U, by a set-screw or other suitable means, so that the vane L Smay be made more or less sensitive to the wind by ad justing the saidweight U.

To the weight U or rod T is attached 'a cord or' wire, V, which passesdown through the barrel 0 and pivot B into such a position that it maybe reached and operated by an attendant to throw the wheel E out of thewind.

To the side of the upper forward corner of the triangular plate Jfarthest from the arm R is attached an arm, WV, which is curved outwardand forward, and is made of such a length that its forward end willstrike against the barrel G, when the vane L comes into a position atright angles with the wheel E, and

' prevent the said vane from moving any farther in that direction.

To the side of the upper forward corner of the triangular frame J,toward the arm R, is attached an arm, X, which projects into such aposition, and is made of such alength, as to strike against the barrel0, when the wheelE has been swung around into a position parallel withthe vane L, and prevent it from going any farther.

' Having thus described my invention, I claim as new and desire tosecure by Letters Patent 1. A windmill, in which the vane L is connectedwith the rotating barrel 0 that carries the wind-wheel by a plate orframe, J hinged JOHN JAMES REED.
